TLDR; Get this one over others
After owlet discontinued the support for older socks, we were faced with a decision I wasn't expecting. After some research we decided to go with eufy, and I'm SO glad we did.We have been using this every night for about a month now, and so here's the in-depth review I wished I could have had at the time I was looking.The sock design is so much better than other ones out there. I have no struggles putting it on since the sensor goes right on the top of the foot. Super simple. I also personally have not had any issues with the sock part being super worn or falling apart either, though she only wears it at night. If it does happen to come off for any reason, the base calmly tells me and there's a little image that lights up. It is so much better than the blaring music of previous products I've had. I personally rely on the base rather than phone notifications and I've had no issues. You can turn off the notifications it does if you want to keep it in baby's room (since it does charge it).It is wonderful for peace of mind, but it does so much more than that. It tells me how good my baby is sleeping, when and how often she woke up, her heart rate, her oxygen, if she's moving around, and how much sleep she got overall.I have my daughter in a mini crib a few feet away and this wonderful base has an image that lights up when she's wiggling, and will stop when she stops. It has helped me not get up every 5 seconds to check on her when I hear noises, making my sleep so much better.I have not had any issues like other people have reported regarding the oxygen sensing. It has never been suspiciously low. The oxygen sensing is in BETA testing so it will NOT notify you if something weird happens on the oxygen front, but you can always look at it in the app. It will notify you of a drastic heart rate change though. I would suggest going into the app settings and changing the heart rate notification parameters a bit so you get an earlier notification if something starts going strange. I love the app. It is simple and straight to the point. You can also invite other people (dad) to have access to see what's going on and be notified as well.The only issue I've had is the sock not charging from putting it on the base a tiiiiny but off. It will make a noise when it starts charging so make sure you listen for it. The battery life is a little over 24 hours, so I have used it on low battery a second night and the base will tell me calmly when it's about to die.For the price, I am so impressed. I would get this over other monitoring systems out there, especially if you can use HSA or FSA funds. Love it so much. So thankful.

Don't waste your $ on Owlet- this one is perfect!!
If you are considering getting a smart sock, don't waste your money on an Owlet. This one does the same thing at a fraction of the price. The app is so easy to use and you can see their heart rate and O2 sat in real time (plus the sleep quality tracking is very thorough). In 5 months, we've only had one "false alarm" telling us to check her heart rate (it was while my husband was holding her, so it was just a weird positional fluke). A voice notification came from the charging base telling us to check the baby, and both of our phones got notified instantly. I am able to sleep soundly at night knowing that if for any reason her sock needs to alert us, the notification is loud and clear. I can't recommend this enough!!

Peace of mind monitoring
I love being able to track sleep and heart rate without paying a monthly fee. The app is clear and the alerts are helpful without being overwhelming. The sock fits comfortably and stays on all night. My baby wears socks over hers. Better price than Owlet

No replacement socks available
We have been using this for about 6 weeks. The pros for me are the peace of mind it provides. I haven’t had any issues with false alarms.I’ve noticed it does not track wake and sleep times correctly. It’s sometimes hard to get the monitor to line up on the charger correctly to charge the device. Also, some time between me setting this up and getting back from the hospital, I misplaced the bigger socks that come with it. I have been trying to find a replacement but they are sold out everywhere. I reached out to Eufy directly on their website and got an automated message that they don’t know when they will back in stock. So I won’t even be able to use this once my baby outgrows the small sock size in a few weeks. Really disappointed by that, and it makes it not really worth the money for me. I wish I would’ve spent a little more and gotten a different system.Edited to add - the seller has since reached out to me and I was able to replace my entire system because it was still under warranty. I appreciate them reaching out to offer a solution.

Better than the owlet
I can not say enough positive things about this product. Let me start with I returned the OWLET SMART SOCK because it kept alarming a connection error or sock placement error every single night. I couldn’t turn off this notification so it wouldn’t alarm me, I only want critical alerts. So I would wake up in a panic when the baby was completely still and asleep due to a connection error. I’m a third time new owlet owner and know all the trouble shooting, nothing helped. The base was 5 feet from the baby on my nightstand, the sock was placed correctly, her feet warm, wifi connection strong. It just kept alarming every night sometimes multiple times. Which defeats the purpose of helping me sleep peacefully.With this monitor not only is the sock itself so much easier to place and get on, but the base and settings are amazing. I like that I can adjust the brightness on the base as well as adjust the sound of notifications to the base and adjust which notifications I want to get on the base and on my phone. AND THEN I can put it in a specific mode for when the baby sleeps in her own room with the base in the room- so it doesn’t alarm in the room waking the baby but will notify my phone. It still monitors all the same trends as the owlet monitor. It holds a good charge, charges quickly and just seems so much better than the owlet for a third of the price. I sleep much better with no unnecessary interruptions.

Not good
First month worked great. Now it randomly loses connection and it’s a pain to connect it back. Also when I place sock on base to charge, then comes the time i put it on my baby, it’s completely out of battery. i’ve checked the app to see if it’s charging and it would be but somehow it never charges.
